What, 2GB of monthly data isn't enough for your laptoppin' needs? Yeah, us either -- fortunately, AT&T's tweaking its phone tethering plan a bit with an extra 2GB that can be shared among all devices for a grand total of 4GB. As before, you'll need to start off with the $25 DataPro plan and tack on an extra $20 for tethering, bringing the total to $45 a month. In conjunction with the move, AT&T has announced that it'll begin rolling out a Mobile Hotspot app starting with the HTC Inspire 4G at its launch on February 13th, which means these guys are finally coming around and embracing the data revolution that's been taking hold the last year or two across the industry -- a trend that began with its first launch of a MiFi a few months back. Existing DataPro tethering customers will get the extra 2GB automatically added to their accounts, so there shouldn't be anything you need to do; obviously, we would've preferred something closer to unlimited, but something tells us that ship has sailed. Follow the break for the press release.
